No laptops are built with desktop CPUs. Not by ASUS, not by anyone else.

Laptop motherboards aren't as standardized as desktop motherboards, they're somewhat consistent in terms of form-factor but the manufacturers have a lot of flexibility. They basically design the motherboard and daughterboards and other PCBs along with the chassis everything fits inside, they can add/remove ports and slots and features just like they do across different desktop motherboard models.

Intel mobile CPUs are sometimes soldered (permanently) in place on board, and sometimes use some variety of "socket". But either way they are not physically or electrically compatible with Intel desktop CPUs. They might have similar Intel model numbers and specs to their desktop counterparts but they're aren't at all interchangeable. They also tend to selected/binned with consideration towards power efficiencies.

Laptop GPUs are often MXM cards. They can be swapped or upgraded. But there are numerous little proprietary differences and issues between them and the motherboards they plug into. It's often easier to just leave them in place and treat them as "permanent" hardware.

hi, thanks for the reply. it is very good reply . but i just would like to know one more thing. this customization of desktop CPUs and GPus for the laptops, does it has some performance impacts?

This is correct. Both Sager and Clevo both offer laptops that have Intel "K" processors in them which are desktop CPU's. As far as Asus offering them, I havent seen any to date, even there very high end GX800 has a mobile "HK" variant.

Very few laptops use desktop parts because the power increases dramatically with those. The performance difference normally isnt significant enough to justify the extra power needed.

u have highlighted also a very good point about mobile CPUs vs desktp CPUs.

i have read somewhere that in the future (already starting with its 8th genertion) intel cpus, desktop ones will have more cores that the mobile ones. so i think that the deskotp ones will have better performance. so maybe asus will reconsider the option of latpops with desktop CPUs.
